Question

1 what is the main purpose of a scatter plot? identify the relative size of data categories determine a direct relationship between data points identify how data changes over time show a general trend in data points

Explanation:

• "Identify the relative size of data categories" is for pie charts or bar graphs.
• "Determine a direct relationship between data points" is not the main purpose of a scatter plot (it shows correlation, not a direct relationship).
• "Identify how data changes over time" is for time - series graphs (like line graphs with time on the x - axis).
• A scatter plot is used to show a general trend (correlation, like positive or negative trend) in data points by plotting individual data points on a two - dimensional plane.

Answer:

Show a general trend in data points
